Common Questions
Lumber and Building Materials: What You Need to Know
Do you stock framing lumber in standard dimensions, or do I need to place a special order?
Oromill carries standard dimensional framing lumber in common sizes used for wall framing, floor systems, and roof structures. For most typical residential and light commercial projects, you should be able to find what you need in our yard. If your project calls for a specific dimension, length, or species that we do not have in stock, we can place a specialty order to source it for you. Our staff can help you figure out exactly what you need before you commit to an order, so you are not guessing at the counter.What is the difference between pressure treated lumber and regular construction lumber?
Pressure treated wood has been chemically treated to resist moisture, rot, and insect damage, making it the right choice for applications where the wood will be in contact with the ground, concrete, or exposed to the elements regularly. Common uses include deck framing, fence posts, and landscaping structures. Regular construction lumber is not treated and is better suited for interior framing or protected structural applications. If you are unsure which type your project requires, our staff can walk you through the right choice based on where and how the material will be used.Can Oromill cut lumber to specific dimensions before I take it home?
Yes. Oromill offers professional lumber cutting as part of our yard services. If you have specific length requirements for your project, we can cut your materials to spec so they are ready to install when you get to the job site. This is especially helpful for homeowners who may not have the tools or space to make precise cuts on their own. Just let our staff know your measurements when you come in and we will take care of it. Keep in mind that we supply and cut lumber to specification but do not build structures for customers.Do you carry plywood and OSB, and what are they typically used for?
We carry both plywood and OSB, which are two of the most common sheet goods used in residential and commercial construction. Plywood is made from layered wood veneers and is commonly used for subfloor, roof decking, wall sheathing, and cabinetry. OSB, or oriented strand board, is made from compressed wood strands and is widely used as a cost-effective alternative for sheathing and structural panels. Both products come in different thicknesses and grades depending on the application. Our staff can help you choose the right sheet good for your specific project needs.Can your staff help me figure out how much lumber I need for my project?
Absolutely. Helping customers with material estimation is something our team does every day. Whether you have a set of blueprints, a rough sketch, or just a description of what you are building, our staff can work through the numbers with you to put together a materials list. This kind of support is something you rarely get at a big-box store, and it is one of the main reasons contractors and homeowners in Whittier have been coming to Oromill for decades. Getting the estimate right upfront saves you extra trips and unnecessary waste.Does Oromill offer delivery for lumber orders?
Yes, Oromill provides delivery service for lumber and building materials through a dedicated delivery truck and driver. Delivery is a practical option for larger orders or job sites where transporting full lumber loads is not feasible. Availability and pricing depend on your order size and location, so the best way to arrange delivery is to contact us directly. Our staff will work through the details with you to find a delivery schedule that fits your project timeline.
